Ok, I'm litterally pissed off here. My subwoofer only makes noise here and there; I was playing iTunes and it quit half way through a song and didn't work again. Then, it started up again and then died. It goes on and off. What the heck? It's a 5 speaker w/subwoofer Altec Lansing speaker system. Is it time to use warranty for a replacement? I checked all connections; replugged, etc. Still the same problem. 5 speakers aren't affected; just subwoofer is messed up.
